how long would it take to travel 100 km at a speed of 50 km/h

Answer: 75.6, 14.4

Step-by-step explanation:

Note 2 angles are complementary if they adds up to 90 degrees. Lets set x to be the first angle.

x - (x - 61.2) = 90

Then we can know:

2x = 90 + 61.2;

2x = 151.2;

x = 75.6

Now we know the first angle is 75.6, we know the second angle is 75.6 - 61.2 = 14.4. Hope you find this helpful!

The probability is 1/144 which can be computed by product of Q-matrix probabilities of transition.

Consider the absorbing states 0 and 6 and utilize both the Q-matrix of transition probability from 1, 2, 3, 4, and 5 to itself, as well as the S matrix of probabilities from 1, 2, 3, 4, and 5 to 0, 6.

The probability of the next three states being 4, 5, 0 in that order depends on the transition probabilities from one state to the next. If we know the transition matrix, we can calculate the probability as the product of the transition probabilities from one state to the next.

Q = Image is uploaded.

Megan tiled a rectangle with an area of 24 square centimeters, the Megan ‘s rectangle is 2 centimeters by 12 centimeters.

Megan tiled a rectangle with an area of 24 square centimeters,

A = 24 square centimeters

Area of the rectangle = length x breadth

A = l x b

24 = 12 x 2

Therefore, length= 12cm and breadth is 2 cm.

The area occupied by the rectangle within its perimeter may be calculated using the formula for the area of a rectangle. A rectangle's area is calculated by multiplying its length by its width (breadth). As a result, the area of a rectangle whose length and breadth are "l" and "w," respectively, may be calculated using the following formula. L * W = the rectangle's area. Therefore, the area of a rectangle is equal to (length width).

Answer:

Step-by-step explanation:

The factored form of a polynomial function with roots r1 and r2 can be found by multiplying two linear factors (x - r1) and (x - r2).

Here are the steps to find the factored form of the polynomial function with roots 3i and 2:

Write the first linear factor: (x - 3i)

Write the second linear factor: (x - 2)

Multiply the two linear factors: (x - 3i)(x - 2)

Expand the product to find the polynomial function:

x^2 - (3i + 2)x + (3i * 2) = x^2 - 2x - 6i

And there you have it, the factored form of the polynomial function with roots 3i and 2 is x^2 - 2x - 6i.

Step-by-step explanation:

Just add the numerators together 10/6. If you need a simplified version it would be 1 4/6.

By evaluating a proportional relation, we can see that if 10 fiction books are sold, then 13 non-fiction books are sold.

Here we know that 3 fiction books are sold for every 4 non-fiction books sold.

Then if x fiction books are sold, the number of non-fiction books sold are given by the proportional relation:

y = (4/3)*x

Here we know that 10 fiction books are sold, so x = 10, replacing that we will get:

y = (4/3)*10 = 40/3 = 13.33

So 13 non-fiction books are sold.

Isaac has a 1/40 chance of winning the raffle, or a 2.5% chance. This indicates that he has a 2.5% probability of having his ticket chosen out of the 40 tickets that were sold.

Isaac has a 1/40 chance of winning the raffle, or a 2.5% chance. This indicates that he has a 2.5% probability of having his ticket chosen out of the 40 tickets that were sold. This is because there is only one raffle winner and it is impossible to predict which ticket will be picked.

It's also crucial to remember that his odds of winning are entirely independent of those of any other ticket holder; nobody else's ticket will affect the outcome of the raffle. As a result, Isaac has the same chance of winning as any other ticket holder. It's also vital to remember that regardless of how many tickets are sold, the likelihood of winning stays the same. Therefore, regardless of how many raffle tickets are sold, there is a 2.5% chance of winning.

Step-by-step explanation:

Since 4104 students are employed sophomores, juniors, or seniors, the total number of unemployed students is 11,989 - 4104 = 7885.

And since 745 students are employed freshman, the number of unemployed freshman is 7885 - 745 = 7140.

So, the total number of freshman is 745 + 7140 = 7885.

The Venn diagram would look like this:

[ Freshmen ] [ Sophomores, Juniors, Seniors ]

[ 7885 ] __________ [ 4104 ]

| 745 |

__________

The sample should be milled to a radius that is approximately 7.19 times its original radius in order to increase its work function by 2%.

The work function of a material is related to its surface area, and milling a sample into smaller nano-spheres increases its surface area. The increase in work function can be approximated by the following equation:

ΔW = kTln(A/A₀)

where ΔW is the change in work function, k is Boltzmann's constant, T is the temperature in Kelvin, A is the new surface area of the milled sample, and A₀ is the original surface area of the sample.

To find the size to which the sample should be milled to increase its work function by 2%, we need to rearrange the equation to isolate the new surface area:

A/A₀ = e^(ΔW/kT)

Plugging in the known values, we get:

A/A₀ = e^(0.02 * 5.1 eV / (8.62 * 10⁻⁵ eV/K * 300 K))

= 51.64

The new surface area is 5064% larger than the original surface area.

Since the sample is being milled into nano-spheres, the new surface area is proportional to the square of the radius. Let's call the original radius of the sample "r₀". Then the new radius is:

r = √(A/A₀) * r₀ = √(51.64) * r₀ = 7.19 * r₀

Step-by-step explanation:

The monthly payment on a loan and the total interest that will be paid during the term of the loan can be found using an amortization formula.

Here are the steps to find the monthly payment and total interest for the given loan conditions:

Convert the interest rate to a decimal: 7.5% = 0.075

Divide the interest rate by the number of periods (months) per year: 0.075 / 12 = 0.00625

Find the number of payment periods: 8 years * 12 months/year = 96

Calculate the monthly payment using the amortization formula:

Payment = Loan Amount * (Interest Rate / (1 - (1 + Interest Rate)^(-Number of Payments)))

Payment = $6,200 * (0.00625 / (1 - (1 + 0.00625)^(-96)))

Payment = $79.88

So, the monthly payment on the loan is $79.88.

Calculate the total interest paid over the term of the loan:

Total Interest = (Monthly Payment * Number of Payments) - Loan Amount

Total Interest = ($79.88 * 96) - $6,200

Total Interest = $7,538.88

So, the total interest that will be paid during the term of the loan is $7,538.88.

The old will Mr Lim be in 6 years time is 46 years old.

To make solving this problem easier, we need to consider the ages of Mr Lim and his son. For example by multiplying the number x.

Let:

Mr Lim's age = a

His son's age = b

So that,

The ratio of ages in the current year:

Mr Lim's age to his son's age = 5x : 2x

a : b = 5x : 2x

The ratio of ages in the four years ago:

Mr Lim's age to his son's age = 3x : x

(a - 4) : (b - 4) = 3x : x

[tex]\frac{a-4}{b -4} =\frac{3x}{x}[/tex]

[tex]\frac{5x-4}{2x -4} =\frac{3x}{x}[/tex]

[tex]\frac{5x-4}{2x -4} =\frac{3}{1}[/tex]

5x - 4 = 6x - 12

5x - 6x = -12 + 4

-x = -8

x = 8

So that we know the age of Pak Lim's and the age of his son's this year.

Mr Lim's age = 5x

                     = 5 × 8

                     = 40 years old

His son's age = 2x

                     = 2 × 8

                     = 16 years old

After that, we find Mr Lim's age 6 years from now by adding 6 years to this year's age.

Mr Lim's age be in 6 years time = 40 + 6

                                                    = 46 years old

Answer:

If csc = 29/21, then the reciprocal of this is equal to the sine of the angle. So,

sin = 21/29.

Since cosine is less than 0, then the angle must be in the second or third quadrant, which means that the sine of the angle must be positive. So,

sin = 21/29, and cos = -√(1 - sin^2) = -√(1 - (21/29)^2)

Next, we can find the tangent by taking the ratio of sine to cosine:

tan = sin / cos = 21/29 / -√(1 - (21/29)^2) = -21/√(841 - 441)

Finally, we can find the cotangent by taking the reciprocal of the tangent:

cot = 1 / tan = -√(841 - 441) / 21

So, the remaining trigonometric functions are:

sin = 21/29

cos = -√(1 - (21/29)^2)

tan = -21/√(841 - 441)

cot = -√(841 - 441) / 21

In a histogram, the width of the bars represents the range of values that fall into each specific category or bin. The spacing between the bars has no meaning in terms of the data being represented.

The ordering of the bars is based on the range of values within each bin, with the bars typically ordered from left to right in ascending order of value.

This is different from a bar graph, where the width and spacing of the bars can have meaning in terms of the comparison of the values being represented. For example, if the width of the bars in a bar graph represents the value of a data point, then a wider bar would indicate a higher value.

The spacing between the bars in a bar graph can also be used to show the relative difference between values. In a bar graph, the ordering of the bars may or may not have meaning, depending on the specific context and the purpose of the graph.

Answer: 200 dollars more

Step-by-step explanation: I did 30% of 500 which is 150 that Noel has.

70% of 500 which is 350. 350-150 is 200

Frank has saved 200$ more than Noel

Answer: 200 dollars

The first step that we should do is divide 500 into 10 separate parts. Each part is 10 percent of the price. 500 divided by 10 is 50.

This means that Frank saved 50 x 7 and Noel saved 50 x 3.

50 x 7 is 350 and 50 x 3 is 150.

Frank saved 350 , while Noel saved 150.To check if we are correct we can add 350 and 150, which is 500 that brings us back to our original answer. Next we must subtract Franks total from Noel to figure out the difference.

350-150 is 200.

This means that Frank saved 200 more dollars than Noel.

6W + W = 770
==> 7W = 770

W = 110 and L = 660 in case you are looking for the solution

Step-by-step explanation:

Let L -= length and W the width of the rectangular field

six times as long as it is wide translates to:
L = 6W

Perimeter of field = 2(L + W)

Given perimeter = 770 feet
2(L + W) = 770
L + W = 770/2 = 385

Since L = 6W, substitute for L in the above equation:
6W + W = 770

7W = 770

W = 770/7 = 110 feet

L = 6W = 6(110) = 660 feet

the width = 55 feet and the length = 330 feet

so basically we take the width as x and the length as 6x then since the perimeter of a rectangle = 2*width + 2*length we will form the equation 6x + 6x + x + x = 770
then we'll solve this equation
14x = 770
x = 55
then multiply x by 6 to get the length which is 330
